Intel VT-x disappeared after upgrading to Windows 8
- by StepTNT
I've upgraded to Windows 8 some weeks ago (MSDNAA!) and today, while I was trying to run a VM, I've noticed that VT-x is disabled.
Now, Hyper-V works without problems, as I've tried emulating Win7 and WP8; but VirtualBox says that VT-x is disabled and it can't run my VM.
Just to double check, I've run Securable by GRC and the Intel utility and both says that I've got VT-x off.
Here comes the problem:
VT-x is ON in my BIOS, and it worked flawlessly before upgrading to Windows 8!
Any kind of suggestion?
